我使用MySQL 5.1.71和Rails 4.0.4在Ruby 2.0.0-p353上运行(通过rbenv + ruby-build),使用mysql2 gem 0.3.15.CentOS 6.5.
在database.yml中,编码设置为"utf8",适配器为所有环境的"mysql2".
我的表都使用UTF-8,"DEFAULT CHARSET = utf8 COLLATE = utf8_unicode_ci".
在Ruby中Encoding::default_internal == Encoding::default_external == Encoding::UTF_8.
关于ActiveRecord为什么还给我ASCII-8BIT字符串的原因,我还能看到其他任何想法？我在Mac上开发了UTF-8,但在Linux上生产的是ASCII-8BIT.
当我启动一个控制台并直接使用mysql2时,我得到了ASCII,所以这似乎是问题所在.
